Does anyone have drop spindles and shackles/hangers

[Hazieview]

I have drop spindles in the front and shackles/hangers in the back. I have some after market 15" wheels in the front and my wheel weights look like they keep getting ground off. What is it hitting on and why? Do I need bigger wheels?

Does anyone have a picture of there truck with this same setup? I'd like to see how good some 20s would fill up the wheel well. (I would put my truck on here but it is in the body shop getting painted)

Thanks guys!
